SYNTHETIC YARN WITH ABILITY OF IDENTIFICATION AND METHOD OF ITS PRODUCTION Russian patent published in 2012 - IPC D01F1/10 D01F6/60 

FIELD: textiles, paper.

SUBSTANCE: synthetic yarn for production of technical fabrics based on polyamide or polyester is declared, and the way of its production. The thread is prepared from a melt of polyamide or polyester with use of a supplement containing the phosphor with a melting point 150-265 °C, put into the melt of the said polymers with the addition of light- and / or heat stabiliser. As the phosphor the thread contains a colourless organic photoluminescent phosphor of a specified colour of glow in the ultraviolet range. A method of producing the thread involves melting of the granules of the said polymer, insertion of additives into it of a light- and / or heat stabiliser, mixing, punching the melt through a multi-channel spinneret followed by a stretching, forming an integrated thread and winding of it on the packing. At that into the polymer melt with the addition of light- and / or heat stabiliser additionally additive is entered that contains a phosphor with a melting point of 150-265 °C.

EFFECT: invention enables to identify the thread in the technical fabric, while maintaining the high quality and strength properties of synthetic fabric.
